After all these years in school‚ I’ve come to discover that I am a math nerd and definitely plan to pursue a career involving numbers. My past Chemistry‚ Algebra and Pre-Calculus classes have helped me come to this discovery. In the future I plan to find a lot more information on different careers to find out what I really want to be. My first career choice is to become a chemical engineer. Recently I’ve been talking to my guidance counselor and asking what careers would interest me due

an alkyl halide. Fischer Esterification is a nucleophilic acyl substitution reaction that converts a carboxylic acid into an ester when the carboxyl group of an acid and the hydroxyl group of an alcohol are condensed with the expulsion of a water molecule. The by product is removed to exploit Le Chatelier’s principle in order to favor the formation of the ester over the starting material.

Abstract The purpose of this experiment is to synthesize isopentyl acetate via an esterification reaction between glacial acetic acid and isopentyl alcohol‚ using concentrated sulfuric acid as a catalyst. The product was washed using sodium bicarbonate and water‚ then dried with anhydrous sodium sulfate. It was then distilled using a standard simple distillation apparatus. The percent yield of isopentyl acetate was 60.39%. This may have been low due to incomplete distillation or evaporation once

Synthesis of Isopentyl Acetate Abstract Isopentyl acetate was synthesized via a Fischer Esterification and purified via simple distillation. The yield was determined to be 25%. The identity and purity of the product was confirmed by comparison of the measured ultra-micro boiling point (140°C) to the published value (142°C).1 Chemical Equation Procedure Isopentyl alcohol (0.787 g‚ 1.2 mL‚ 8.93 mmol)‚ acetic acid (1.574 g‚ 1.5 mL‚ 26.20 mmol)‚ and sulfuric acid (0.368

aMicroscale Synthesis of Isopentyl Acetate (Banana Oil) Objective: Carried out the microscale synthesis of isopentyl acetate by direct esterification of acetic acid and isopentyl alcohol. This was an acid catalyzed Fischer esterification. Both extraction and distillation were employed to obtain a pure product. IR spectroscopy and gas chromatography were used to determine purity of the final product. Reagents: * Compound: | * MW (g/mol): | * MP (°C): | * BP (°C): | * Density (g/mL):

2013 Abstract The purpose of this lab was to determine whether a sufficiently pure sample of synthetic banana oil could be prepared through Fisher Esterification. During the experiment‚ the reaction mixture was purified through an extraction workup‚ and according to the instructor‚ once getting the density of the product and the actual yield; it was not required to use the distillation method.

along with the aqueous layer when the aqueous layer was getting separated from the organic layer by a pipette. One of the methods that favors the formation of an ester can be made by adding excess acetic acid and another method is conducting Fischer esterification‚ which water will be removed to form the ester. There are several ways to have more isopentyl acetate. First‚

Experiment # 45: Benzocaine Abstract The local anesthetic‚ benzocaine‚ was synthesized via the esterification of p-aminobenzoic acid with ethanol. The percent yield of crude product was determined to be 21% and the melting point was recorded at 86.2°C ± 0.2°C‚ with a 6.3% error from 92°C‚ the literature melting point of pure benzocaine. The crude product was then recrystallized to improve the purity of benzocaine and 57.4% was recovered. The new melting point range was measured at 89.1°C ±
